An estimate of the low-gravity solids content of the mud cleaner screen discard can be made by weighing the discard. Since the solids concentration will be around 60% volume, the mud weight will be a reasonable predictor of the low-gravity solids concentration. For lowgravity solids with a specific gravity (SG) of 2.6 and a barite SG of 4.2,
The weighted mud flows to the inlet head section of the desander and/or desilter entering the hydrocyclones for separation of particles. Mud leaving the underflow is further screened with fine mesh to separate larger particles allowing only barite size particles to pass through the screen returning and recovering then the clean mud.
The purpose of the mud cleaner is to remove drilled solids larger than barite. Mud cleaner could be useful cleaning facility at many filed of mud management.
Mud cleaner used in oilfield means the equipment processing drilling mud. It is combined with desander cone and desilter cone as well as bottom shaker. It is called 2nd and 3rd phase solids control equipments.
